Description

Hybrid vehicle dual input planetary transmission device
Affiliated technical field
The utility model relates to the planetary type gear transmission unit of a kind of hybrid electric vehicle engine and motor double input.
Background technique
At present, hybrid vehicle adopts motor is linked to each other with traditional mechanical transmission.Though having continued to use traditional speed changer, this layout make the manufacturing inheritance good; But the size that has traditional speed changer is big, gear shift is difficult, the size of motor is also big, the more high deficiency of failure rate of machinery.
Summary of the invention
The utility model provides the planetary gear construction transmission device of a kind of hybrid vehicle by motor and motor double input.
The technological scheme that the utility model adopted is: connect planetary type gear transmission unit in the automobile clutch back.In this device, motor shaft links to each other with planet carrier by main, driven gear; Be meshed with the output shaft sun gear with motor input shaft sun gear respectively by three uniform double-planetary gears.Arrange a break on input shaft and planet carrier respectively, brake casing links to each other with the drive unit shell.
Hybrid vehicle of the present utility model is divided into low velocity zone, middling speed district and high velocity by the speed of a motor vehicle: input shaft is braked by break, motor power is slowed down for the first time through active and passive gear, be delivered to through planet carrier again and export by output shaft after planet wheel slows down for the second time, constitute the low speed of a motor vehicle operating mode of machine operation; Planet carrier is braked by break, made engine power reach double-planetary gear,, constitute speed of a motor vehicle operating mode in the engine operation by output shaft output through input shaft; Two breaks are all discharged, and motor and motor are united participation work, are outputed power jointly by double-planetary gear and planet carrier, constitute the high speed of a motor vehicle operating mode of joint work.
The utility model characteristics are that the gear that adopts is few, only need four cylindrical gearss and three duplicate gear transferring power, just can cover the vehicle speed range of the full operating mode of hybrid vehicle.Less than the big ring gear of diameter, can reduce the planetary gears external diameter; Planet carrier structure is simple; With three pairs of duplicate gear engagements, reduced the diameter of input shaft gear and output shaft gear; Select suitable helix angle, the axial force of duplicate gear can balance; More than each factor all make the transmission device overall dimensions reduce, in light weight.Because motor through the double reduction transferring power, can adopt the high-speed electric expreess locomotive weight reduction; External motor has reduced low cost of manufacture, good reliability.The utility model is applicable to the transmission system of various hybrid vehicles, so applied range.

Embodiment
In Fig. 1, the housing 3 of transmission device of the present utility model links to each other with clutch 2 housings, and the front end of input shaft 12 is connected with the clutch driven plate spline, and inserts in the bearing of motor 1 crankshaft rear end; The other end of input shaft 12 links to each other with sun gear, and with the engagement of the gearwheel of double-planetary gear 6; Motor 11 links to each other with planet carrier 9 through driving gear 10, driven gear 5; The sun gear engagement of the small gear of double-planetary gear 6 and output shaft 8.
When break 4 brakings, break 7 are the low speed of a motor vehicle operating mode of machine operation when discharging.Motor 11 power drive the output of output shaft 8 sun gears through driving gear 10, driven gear 5 transmission planet carriers 9 by double-planetary gear 6.
Can analyze the drive connection of the low speed of a motor vehicle operating mode of machine operation by Fig. 2 and Fig. 3 a.The velocity ratio im of motor 11 rotation speed n m and output shaft 8 rotation speed n o is
i m = n m n o = r 2 r 5 ( r 3 - r 1 ) r 3 r 4 ( r 2 - r 1 )
This operating mode makes full use of the characteristic of motor low speed high torque, and through twice deceleration, so vehicle is in low speed driving; This moment, the driving force of vehicle was big, and vehicle acceleration is also big.
Break 7 brakings, break 4 are speed of a motor vehicle operating mode in the engine operation when discharging.Because planet carrier 9 brakings, motor 1 power are delivered to the output of output shaft 8 sun gears by input shaft 12 after double-planetary gear 6 slows down.
Can analyze the drive connection of speed of a motor vehicle operating mode in the engine operation by Fig. 2 and Fig. 3 b.The velocity ratio ie of motor 1 rotation speed n e and output shaft 8 rotation speed n o is
i e = n e n o = r 2 ( r 3 - r 1 ) r 1 ( r 3 - r 2 )
This operating mode speed of a motor vehicle is a vehicle driving moderate speed range commonly used, as 40km/h to 50km/h, will guarantee that therefore motor always is in low oil consumption work down.
Can analyze the drive connection of motor-high speed of a motor vehicle operating mode of motor joint work by Fig. 2 and Fig. 3 c.Break 4,7 all discharges, and this moment, double-planetary gear 6 was subjected to the driving of uniting of motor 1 and motor 11.Its output shaft 8 rotation speed n o that unite driving are
n o = n e i e + n m i m
Be that motor 11 works independently when vehicle backing, identical during the low speed of a motor vehicle operating mode of its break braking and drive connection and machine operation, the direction of rotation of motor 11 only.
Can analyze the engine-driving electric power generation to the battery charge operating mode by Fig. 2 and Fig. 3 d.Brake wheel when vehicle stops to discharge break 4 and 7, and the velocity ratio ic of motor 1 rotation speed n e and motor 11 rotation speed n m is
i c = n e n m = r 3 r 4 ( r 2 - r 1 ) r 1 r 5 ( r 3 - r 2 )
Now nondimensional Pitch radius being carried out the calculating of each velocity ratio compares.If r1=r4=r5=1, r2, r3 that different proportion is concerned calculate each velocity ratio such as following table.
The velocity ratio of showing under each Pitch radius proportionate relationship calculates relatively
r1 0.8 0.7 0.6 0.5 0.4
r2 0.9 0.85 0.8 0.75 0.7
r3 1 1 1 1 1
r4 1 1 1 1 1
r5 1 1 1 1 1
Im 1.8 1.7 1.6 1.5 1.4
Ie 2.25 2.428571 2.666667 3 3.5
Ic 1.25 1.428571 1.666667 2 2.5
As seen from the above table, each velocity ratio is in suitable scope, so the utility model can be set up.
